  1. Flexible notation for inputting literal numbers in Tachyon

    Forth is very flexible with inputting and outputting numbers in any base, the most common being decimal, hex, and binary. Normally you just set the base you want but sometimes you want to make sure that no matter what the base is set to that a number is recognized correctly. Other times you may want a number to be more recognizable such as 80,000,000 and so on.

    So here's a quick introduction to the way we can specify how literal numbers are handled on input into Tachyon, which makes ...

  2. Propeller Tool Serial Communication

    by , 10-21-2014 at 06:00 PM (Learning Verilog and Propeller-like Core Designs)
    While working on a programmer application for the P1V (and the Propeller), I started wondering how the serial communication was actually working. What I found was rather ingenious, so I thought I would write up the details. This should be of interest to anyone working on the P1V, as well as anyone needing to develop a simple serial protocol for their own projects.

    To start, let's cover the basics. Communication with the P1V is achieved with a standard serial configuration: 8N1. ...

  3. 48 leds on a single propeller. MimsMirror:ZeroHD

    I have tested expanding a zero into double the leds to be a zeroHD.
    It works very well.



    This is a MimsMirror:ZeroHD
    It has a total of 16 RGB leds, making this propeller chip control 48 individual leds directly.

  4. What I have in mind for my GeoRover

    by , 09-09-2014 at 01:20 AM (Propeller-Powered GeoRover Inspection Robot)
    I have long planned to do much like the Beatty Robotics' Trekker, featured at http://beatty-robotics.com/all-terrain-gps-robot/. This is a great design, based on the Wild Thumper platform. Robert Beatty and his two girls are doing really great things over at their shop, as can be seen at their website. Check it out when you can.

  5. Propeller 1 Verilog Round-up

    by , 08-31-2014 at 06:48 PM (Learning Verilog and Propeller-like Core Designs)
    Since the source for the Propeller 1 has been release, there has been a mariad of activity on the forums. In fact, there has been so much activity that I am starting to lose track of key posts, files, etc. So I am creating this entry to keep track. While this is mostly for my own benefit, I hope everyone else will also find it useful.
